I don't blame the catchers, they are just doing their jobs, but I have said for a few years that I think the sport will instantly become maybe 30-40 percent more enjoyable (for me anyway) once an accurate electronic strike zone is implemented. It's not just the incorrect calls, sometimes game-changing, it's also that there is a whole category of pitches meant to be out of the zone but trick the ump into calling them strikes. With an electronic zone, that category would immediately disappear, as there is no one to trick, also probably speeding up the game. Tom Glavine would have had to retire years earlier.
Anyway, tennis fans can testify as to how the sport is somewhat better now that it is essentially all electronic calls with no real challenge system, as the electronic system is already making the call. The athletes no longer can logically complain about the calls and slow down the match (the crazier and more entertaining ones still find a way occasionally) so it is more sport and less bullshit. I think this would/will be an even stronger effect once it's in MLB, I can't wait.
And when that day comes, Jose Trevino and Austin Hedges can maybe get coaching jobs...
